To all whom it waag concern;`

l Be it known that LCLARE'NGE BJ Honoris, v

a citizen of the United States, residing at Detroit, inthe countyof'Wa-yne and State of Michigan, have invented certain new and usefulImprovements in Force-Feed Lubri-l icators, of which the following isaspecifica'- tion, reference being had therein to theac-- .'companyingdrawings..

The invention relates to improvements in force-feed'lubricators; and 'itconsists in the lconstruction of such a lubricator comprising a L.pumpand valve mechanism for forcing the o' tothe desired point. A

.The invention further consists in the construction of a valve mechanismwherebythe usual check-valves are ,dispensed with-,'and, further, 1n apump mechanism inwhich a single shaft-acts as a valve-shaft and anapertured device forthe ump, and, further ,in theconstruction ofa evicein which apsingle ump takes the oil from' the reservoir, passes 1tthrough a sight-feed device, and takes the oil from the. sight-feeddevice 'and delivers it to the oint to be lubricated.

'ffl The invention further consists in the con-l struction, arrangement,and comblnati'onl of the various'parts, as more fully hereinafterdescribed, andparticularlyy pointed outy in l thehlaims.

In' thedrawings, Figure 1 1s a vertical oo n-V tral 'cross-sectionthrough my. improved lubricator. Fig.' 2 is avertical central sectionthrough Fig.A 1. fFig. 3 is a cross-section on line, 3 3, Fi 2. Fig. 4is a horizontal section central y through the valve-shaft and showingthe piston in elevation.

- A represents'the reservoir, whichin this oasecontains the pump andvalve mechanism. At .the bottom of the reservoir and transverselythereof is a conical valve-casing B,v in which is the conical valve B.This valve has the shaft C, extending .through one end, and to thisshaft anyv suitable drive mechanism may be attached for rotatmg 'theshaft, .y

C isa piston working in a cylinder C, i

formed longitudinally and axially of the valve. This piston I have"shown in the shape of a plain shaft which extends to the loutsidethrough the casing D, passing through an annular nut D', and at theouter end provided with the 4usual packing-gland D.

i This piston is provided with a lug E, engaginl in a slot E in theextension F of the Ava ve. Sleeved on the piston C are the twoSpecification of Letters Patent. replication f'iiediimh 11,1905. serialN'o. 249.594.

collars-G and G', `both-these collars being held from movement and theshaft. rotating therem. Between the two collars, the proximate faces ofwhich are prolp'erly shaped,.isa

camway H, in which trave the roller-wrists 1 which' are xed to thepiston.

I is a spring bearing at one end against the 'collar G and at the otherendfagainst theend of a valve to hold the valve ti htly to its seat.

At the in er endy of .the cy inder the valve is provided with a lateralport a. The valvecasing is provided with a port b,`leading into thereservoir, and a final exit-passage c, 4through which the oil isdelivered to the point to be lubricated. Extending. up. from. thevalvefcasii'ig is a sight-feed passage d, the

upper end of which connects into a transverse lpassage d at the top ofthe reservoir. At the' other end this passage is provided with aspringfseated check-valve e, controlling the port leading back into thereservoir. From the passage d is the nozzle h, which is adapted todischarge oil through the sightfeed chamber i, rovidedwith the bulls-eyeglasses i. At t Le bottom of the sight-feed chamber -is the passagec,'which leads back tothe valve-casing. The passages d d', the nozzlehf, the sight-feed chamber i', and the return'passage 1c l refer to as asight-feed passage leading from and returning to the ycontrolling-valveof the puinp.

The oil passing from the passage d through the nozzle is controlled by aneedle-valve l,

reservoir and motionbeing imparted to the shaft C, (or to the shaft C',if desired,) the valve will be rotated, and with it 4the pis. tonfC. Theport a in the valve will first register with the inletfport b, and atthis point the .piston C will be moved outwardly, so that it will drawthe oil. from the reservoir into the cylinder. The valve then rotates tothe position shown in Fig. l, the port a registering with ythe passaged, Aand during this registration the pis ton is moved inward, so as toforce the oil drawn from the reservoir into the sight-feedpassage. Theport a in the continued rotation of the valve then registers with thereturn-passage 7u, and the piston is yagain moved outward, drawing theoil from `r oo l sight-feed'passage, so that the' operator may ,know howmuc sure: will` lift the check-valve I S with a fillingobvious that itmay` be embodiedin many nection device for rotating ,passy therethroughthan is h oil is being fed,and then' take upfagain the oil thus pumped'and def. vlivei` it out tothe p`oint"to belubricated.

. Incase the valve l is set so Vthat less oil 'can umpedinto thesight-feed'p'a'ssage, the surplus under pres? from 'its seatandfall-back into'th'e reservoir to be pumped overag'ain. j, -I mayprovide the "device with any suitable gage-glass, such as'shoWn at-M,Fig. 2, aridv aperturefas shown atv N, Figi?. The specific form.ofdevice here shown is butv one embodiment of niyinventioin` as it isdifferent forms, as I believe in its broader phases my 4invention isquitegenericf as to certain features; of construction, which Ihavepointed out in the claims.
